ROUTING 1V[ACHI1\TE.

A lication filed October 12, 921. Serial No. 507,260. i

7 '0 all whom it may concern: I

Be it known that I, LESLIEH. GALE, a citizen of the United States, residing at Worcester, inthe county of WVorcester and State of Massachusetts, have invented a new and useful Routing Machine, of which the following is a specification.

This invention relates to a machine f0 routing printing plates.

The principal ob3ects of the invention are to provide a machinefwhich will rout either curved or fi'at plates without reorganization of the machine and with the employment of a very simple adjustmentg to provide an improvedarrangement for lifting the routing head; 'toprovide improved driving means land adjustments therefor for operating the routing tool and an improved toolhead; and generally to provide a simple and practical machine] capable of performing all the operations necessary in routing either curved ing drawings, in which F1g.,1 1s. a side view of a-routing ma- The invention also involves improvements in various details of construction of the machine.

Referenceis to be had to the accompanysame position, that is, the position for routing a flat plate;

Fig. 6 is a similar view of the same in section showing the parts in position for routing a curved plate; h v

Fig. 7 is a side elevation on enlarged scale showingv the routing tool support and driving devices, and a Fig. 8 is an elevation on. enlarged scale of the routing head.

In order to provide routing mechanism locatedat theproper elevation and in convenient position for operation I prefer to employ a cast metal base 10 adapted to rest on the floor and supporting a routing table clamps.

11. This table is provided with a series of holes .or depressions 12f0r the reception of stops for holding the edge of a flat plate, and is also provided with a rece ss' 13 in which is journalled a plate support 14. This support has a flat top 15 provided with a dovetail groove 16 for a plate clamp 17 of any desired character. NVhen a flat plate is to be routed it rests partly on this support and partly on the table 11 with which the flat top of the support 14 is flush. The support is also provided with a projecting portion, preferably of curved form, for supporting a semi-circular or other curved plate, and this has grooves 18 for plate These grooves are so located as to receive curved plates of different diameters to be clamped on the support.

The plate support 14: is mounted on a shaft 20. This shaftis provided with a gear 21 operated by a worm 22 on a shaft 23. A hand wheel 24 on the shaft is employed for turning the gear and shaft so as to turn the plate-holder from the position shown in Fig. 5, forexample, to that shown in Fig. 6.

The shaft 20 is mounted in a pair of brackets '26 carried by the table. A bracket 25 supports the shaft 23 also.

the reception of a slide 35. This slide is not fixed in position, but is capable of moving out and in at will, and is also capable of sivingingup and down about the stud 33 freey. f

. On the end of this slide there is a verth cally slid-able head 36 which carries a hollow shaft 37 that supports the routing tool 38 below. This routing tool is driven by a belt 10 from a motor located on the machine or from a countershaft as desired and operating on a pulley 41. This pulley is slidably keyed to a shaft 42 which is journalled in a U-shaped bracket 43 pivoted on the horizontal stud 33. The shaft 42 passes into pivoted thereon on a vertical axis, a horizontal stud on said bracket, a bracket pivoted on said stud and having a pair of bearings, a shaft slidably mounted in said bearings and adapted to swing about said stud, means for driving said shaft, a guide also pivoted on said stud, a slide movable along the guide, a routing head carried by said slide, and means on said shaft for operating the routing head.

In testimony whereof I have hereunto affixed my signature.

LESLIE H. GALE.
